swyx here. we got some preview and time with the API/DX team to ask FAQs about all the new APIs.

https://latent.space/p/openai-agents-platform

main fun part - since responses are stored for free by default now, how can we abuse the Responses API as a database :)

other fun qtns that a HN crew might enjoy:

- hparams for websearch - depth/breadth of search for making your own DIY Deep Research

- now that OAI is offering RAG/reranking out of the box as part of the Responses API, when should you build your own RAG? (i basically think somebody needs to benchmark the RAG capabilities of the Files API now, because the community impression has not really updated from back when Assistants API was first launched)

- whats the diff between Agents SDK and OAI Swarm? (basically types, tracing, pluggable LLMs)

- will the `search-preview` and `computer-use-preview` finetunes be merged into GPT5?

A bit off topic but the post comes handy: can we settle the debate what an agent really is? It seems like everyone has their own definition.

Ok I’ll start: an agent is a computer program that utilized LLMs heutiger for decision making.

an agent is software that does something on behalf of someone (aka software)

I personally strongly prefer the term "bots" for what most of these frameworks call "agents"

They did not announce the price(s) in the presentation. Likely because they know it is going to be very expensive:

   Web Search [0]
    * $30 and $25 per 1K queries for GPT‑4o search and 4o-mini search.

   File search [1]
    * $2.50 per 1K queries and file storage at $0.10/GB/day
    * First 1GB is free.

   Computer use tool (computer-use-preview model) [2]
    * $3 per 1M input tokens and $12/1M output tokens.

Notably not mentioned: Model Context Protocol https://www.anthropic.com/news/model-context-protocol

not implementing doesn't mean its not supported https://github.com/dylibso/mcpx-openai-node (this is for mcp.run tool calling with OpenAI models, not generic)

but yes, it's the strongest anti-developer move to not directly support MCP. not surprised given OpenAI generally. but would be a very nice addition!
